LUCKNOW, April 14 -- At least six people were killed and seven others critically injured after a speeding truck rammed into a bus carrying a wedding party and overturned on it in Uttar Pradesh's Hapur district early on Monday, police said. According to police, the accident occurred around 1:30 am on the Dhaulana-Gulawathi road, around 22 km from the Hapur district headquarters under the Dhaulana police station area. Hapur SP Gyananjay Singh said the bus, carrying around 20 wedding guests, was returning to Ghaziabad's Dasna after a marriage function in Bulandshahr's Gulawathi when the tragedy occurred. "Prima facie, overspeed and poor visibility appear to have led to the accident," the SP said. The police said the bus had been stationed on the roadside on a narrow stretch when the truck, coming from the opposite direction at high speed, crashed into it. The impact caused the truck to overturn onto the bus, crushing a portion of the vehicle and trapping several passengers. Local police and rescue teams rushed to the spot after being alerted by other wedding guests who were standing outside the bus. Some passengers were evacuated after breaking the bus windows, while others had to be rescued using gas cutters as they were pinned inside the mangled vehicle, officials said. The injured were first taken to the Dhaulana community health centre and later referred to Rama Medical College, Pilkhuwa, and GS Medical College for advanced treatment. Dhaulana SHO Avneesh Sharma said seven people were critical. He said the deceased were identified as Yunus, 50, Yusuf, 55, Akhtar, 40, Sonu, 25, and Munna, 60. All five deceased and seven injured are from Dasna in Ghaziabad, police said. He said the sixth person who died in the incident was the truck driver and his identity was yet to be confirmed....
